Problem including: thread, native calls, web service

Question

I have the following problem:
There is web service (myService) running on a 2-processor machine
The web service starts a thread (myThread)
The thread's run calls a native method (myNative).
The implementation of the native method simply calls a function (myFunc).
The web service starts the thread and waits for it to end (with join() ).
The above are summarized in the following:
myService
myThread.run()
myNative()
myFunc()
The problem is:
it seems that while myThread has ended its execution, the myNative function keeps running.
(e.g. messages of myNative are printed after the end of the execution of myThread)
Could this be related to the fact that the machine has 2 processors?
What could be the cause?
Thank you in advance.

Answer 1

This is most likely caused by how the native processes standard output streams are implemented. Try using some other form of feedback (i.e. write to a file, or throw up a user dialog box) and you'll most likely see that the native method is indeed returning when you think it should, but the native output stream doesn't show up until later.
